take off bc, hold it in front of you and work the valve on and off as you rise slowly to the surface..
done it!

Then go to your "Safe Second Octopus", or your Buddy's. . .
(And I mean a Diver should be taught "The Right Way" on such contingencies straight out of Basic Open Water. . .)

Marek K:But... but... Mr. Kev... what if I don't dive a long hose or bungied back-up?
(You mean, of course, that a diver shouldn't be diving that sort of conditions unless tech-trained and -equipped... right?)
Since he's talking about (in that part of answer) what he'd do in doubles, you SHOULD have a long hose and bungied backup in that case. Can't imagine anyone is diving doubles with a standard reg and an AIR2
Web Monkey:
And I was pretty sure that's what you meant. It wasn't so much the "keep you safe" part I was objecting to. It was the "responsible" part.
Putting your buddy in the context of "back-up brain" is the right idea. The primary brain (yours) is responsible for keeping you safe. The alternate brain (buddy's) is only deployed in case you experience a primary brain failure or, the not uncommon OOB - "out of brains" situation.
Kevrumbo:
"D - None of the above"
On a single tank with standard valve: shut down valve and switch to the 40cf bottle you're slinging under your left arm and safely end the dive, while making deep stop for one minute and completing a three minute safety stop.

I like that one Mike, that's what I would do.

Why Kev? You can't do it?

Another scenario: You're at 100 feet, cold water, low viz, diving a single 130, and your primary reg freeflows and you can't get it to stop.
Where I dive it's basically most of the time low vis, cold, so our equipment arrangements are set up for that. The diveleader (the person leading a buddy pair) has to have a doublve valve setup on his single tank or double tanks with 2 separate 1st/2nd stages. This is mandatory... for the other divers it is strongly encouraged to have the same setup (most have realy).
So with this setup in mind:
1) Main reg starts freeflowing (doesn't matter if it's the 1st or 2nd stage... I don't think you'll be able to determine that in the few minutes before the tank is empty).
2) I switch to backup reg (which is a separate 1st-2nd stage on a separate valve).
3) I try to close my main valve asap. If I can't reach it soon enough my buddy (since we dive buddy lines most of the times will be right near me) will follow the hose from my freeflowing 2nd stage to the first stage and valve and close the valve (in limited vis with alot of bubbles flowing the easiest way to avoid mistakingly closing the wrong valve (of the backupreg).
4) Check manometer to see how much pressure was lost. Start ascend to surface on own backupreg if enough pressure left otherwise use backupreg buddy.
5) After a couple of min at a shallower depth you can try to reopen the valve of the freeflowing reg. There is a good chance that it will have thawed by then.
Looking over my response I realise that I need to urgently practise the closing of valves under water on a single tank again. This realy is a very important skill to maintain.
Cheers

I have a good scenario you are doing a solo dive in moderate visability, slight surge and at a depth of about 40 feet. You then become entangled in a monofiliment fishing net that was not clearly marked on the surface (poachers). This net is tangled in the valves of your doubles rig....what do you do?
